What's the difference between the blender knife assemblies: AP3193985 vs AP2803757 besides the price? The pictures look identical.
Answer Hello Jay! Unfortunately, we do not have all the specs listed available for these two parts from the manufacture. Searching Bosch's manufacture information for their MUM60 models, the correct drive knife assembly for these models are 00054246. It is suggested to replace the correct part on your appliance. Thanks.
